TUSCALOOSA -- LSU backup quarterback Ryan Perrilloux, who plays a significant role coming off the bench as a dual-threat quarterback, won't play Saturday against Alabama.

LSU coach Les Miles made the announcement to reporters in Louisiana following Wednesday's practice.

Perrilloux was present during a weekend brawl at a Baton Rouge, La., nightclub. Baton Rouge police said Wednesday he would not be charged in the altercation.

Miles also said backup linebacker Derrick Odom and walk-on Jeremy Benton had been dismissed from the team. Odom was charged with a misdemeanor stemming from the incident and has had brushes with the police in the past. Benton was also present at the incident.
